A lot of acronyms in my subject line, but you probably already know what I'm asking.
Can a single Bluetooth GPS receiver "talk to" two independent Bluetooth capable devices at the same time?
My wife and I both have Treo 650s and I just bought a Globalsat BT 338 receiver. I haven't tried the experiment yet, and BT is so mysterious to me that I can't figure out whether or not this should work. Anybody know?

Don't quote me on it but I think that www.gpsgate.com can "re-broadcast" the gps info. Ask the developers.

Actually I believe it is possible. I have no experience with either of the products you mention, but technically it should be possible.
You would pair the GPS with one of the Treo's and then use GPS gate to "split" the data to 2 serial ports... One local and one BT "outgoing" port. You could then pair both Treos and have the second one read data from the first.
I'm sorry if this isn't very clear, I'm not sure I'm using the correct technical terms to explain. Please let me know if you don't understand, I'll try to explain some other way.

Ricardo,
You are correct it did work. This is how I did it :
I am using an iPaq 5550 running 2003 and iPaq 5455 2002 both units running GPSGate, GPS used RoyalTek 2001 SIRF III.
Unit 1 5550 activate Bluetooth, in GPSGate input COM 8 baud 57600 output Virtual Ports COM 4.
Unit 2 5455 activate Bluetooth pair 5550 and 5455 together, in Bluetooth connect to Unit 1 (iPaq 5550) to serial port, in GPSGate input Virtual COM 4.
Both units now receive GPS signals from the RoyalTek 2001t.

FWIW, Emtac's Trine BT GPS can supply data to multiple devices, IIRC three max.

Darren,
Thanks, I know that but this was a test which many said could not be done. Actually I asked the same question a couple of months ago and no one could give me an answer. Well at least I am happy using one GPS on 2 different units not just one GPS used to split GPS signals usable in different programs on the same unit, that was too easy.

AFAIK a single bluetooth transmitter can only connect to one device. However, you could connect two bluetooth transmitters to a single GPS with one of these http://pc-mobile.net/gdy2.htm and two of these http://pc-mobile.net/bta.htm
You'll need a GPS which can deliver 4800 baud NMEA data. I have one of these PC-Mobile transmitters, and it works very nicely.

Tim,
I personally think GPSGate is a better solution, first of all it's software not an add on box which I'll have to carry with me and secondly GPSGate it's price is right :-)

No. The bluetooth standard allows up to 8 connections from any device. It is the choice of the implementor of the interface whether he wants to write the code to support that. And since time is money, most only implement a single connection.
